High-speed block bottom valve sack machine for cement, chemical, fertilizer, mortar and building material packaging. Stable output of 120–130 bags/min with surgical-level servo precision, standard AI visual inspection and scrap rate below 0.1% — powered by patented, independently developed design.
Stable Speed
Dynamic Error
The HSFK-J1-FK008-VS is a high-speed precision block bottom valve sack system for cement, chemical, fertilizer, mortar and building material packaging. It runs stably at 120–130 bags/min, with millisecond-level control, surgical-grade servo precision (2kHz response, <0.01mm dynamic error) and intelligent energy saving of 10–30%.
Innovative bag opening technology combines adsorption with conveying for efficiency, stability and long life. The unique heat sealing system keeps air blowing uniform and temperature constant for higher weld quality — nozzle width adjustable in 1mm units without stopping, and single-sided lamination heat-sealed easily.
A standard AI visual inspection system detects fabric and bag-making defects and rejects defective bags online. Independently developed with 200+ national patents and avoiding 20+ foreign patents — completely independent IP with no infringement risk; control system free upgrades for 3 years.
Suitable Material：PP/PE tubular woven fabric (single or double-sided lamination), with valve sticker and bottom sticker.

Super computing power with millisecond scanning and large-scale I/O expansion. Instantly processes massive signals and coordinates multiple motors — efficiency +30%.
2kHz speed-loop response and <0.01mm dynamic error deliver needle-level positioning at 120–130 bags/min — skew-free sealing, burr-free cutting, scrap reduced 50%.
4K line-scan camera with AI adaptive recognition. Detects base fabric defects (holes, joints, running weft/warp, missing yarn, scratches) and bag defects (patch offset, patch fold, bottom not formed). Missed detection <0.05%.
Combines adsorption with conveying system, dual-servo segmented control, opens both sides of the bag mouth at a fixed angle — high efficiency, stability, long life, easy maintenance.
Uniform air blowing and constant temperature. Nozzle width adjustable in 1mm units without stopping; single-sided lamination heat-sealed easily — higher, consistent weld quality.
All functions driven by independent servos: bag width, valve position and bottom sticker position adjustable on the touchscreen — one-click spec change, no stopping, no sticker folding.
Passive unwinding with magnetic powder brake, imported edge corrector (deviation ≤±1mm), roll-end alarm, auto stop on material break while keeping tension.
